Boston Bruins general Peter Chiarelli had no update on the status of defenseman Aaron Ward today. Ward left Saturday’s game one shift into the second period after he hit Buffalo center Matt Ellis. Head coach Claude Julien called the injury a “slight charley horse” after the game. Chiarelli said the club should have more info Monday.

Chiarelli also reiterated what he said about winger Marco Sturm in a published report today — the veteran will have knee surgery soon. Sturm has been out since he last played Dec. 18. When asked about the seriousness of the injury, Chiarelli would only say, “He’s going to have surgery and when it happens we’ll give you an update.”

As for the report that center Patrice Bergeron, out since Dec. 20 with a concussion, is doing light exercise and riding the bike, Chiarelli confirmed that the biking has taken place both at TD Banknorth Garden and Ristuccia Arena in Wilmington — a good sign for Bergeron because he’s been able to get out and about. As for the next step on his road to returning from his second concussion in as many seasons, Chiarelli said that there’s a protocol in place — as there is for all head injuries — but at the end of the day the team defers to the feelings of the player.

When Bergeron begins to feel able, he’ll have to do “activity at a certain heartbeat rate for a certain period of time over a certain number of days. And then there’s a certain period (he has) to be symptom-free,” according to Chiarelli.
